Bearing and Components

Bearing and ball bearing is one of the most important parts of industrial machinery. They are used by all industries, from little to large, to smooth the movement of mechanical parts. Bearings are crucial in decreasing friction between moving (ROTATING) parts. In other words, every object in the world, except the Earth and rotating electrons, utilizes bearings.
In bearing production, Grinding, components assembly method, quality of raw materials (material alloy), heat treatment technique, and post-production heat treatment, all play major roles in the quality, performance, and pricing of bearings.
Aside from selecting a reputable brand, installation (Initial mounting and lubrication), alignment, re-lubrication, condition monitoring, and replacement all have a substantial impact on the bearing life cycle.
CB Iran Trading Company is ready to give services to industries as the official sales representative of SKF’s products in Iran, including bearings and all types of accessories.

Types of bearing

Types of Bearing

Bearings are classified according to their function and characteristics, such as the needed speed and accuracy, axial, radial, and vertical loads, lubrication conditions, heat tolerance, installation space, usage environment, and so on.

Ball bearing: bearings with a spherical moving component (ball)

Deep groove ball bearing

 Deep groove ball bearing

These bearings are used in a wide variety of  applications; they are the most common and are appropriate for high and extremely high speeds. They can accommodate moderate radial loads as well as axial loads and require little maintenance.
 Angular contact ball bearings

 Angular contact ball bearings

Internal and external rings in these bearings move relatively to each other in the direction of the bearing axis. This means that these bearings are built to endure radial and axial loads as well as combined loads. The axial load bearing capability is directly related to the size of their contact angle.
Self-aligning ball bearings

Self-aligning ball bearings

These bearings are made up of two rows of balls, each with a groove on the outer ring and two grooves ON the inner ring. They are less affected by misalignment. As a result, they are appropriate for applications where there is a risk of error owing to installation or shaft deviation.

Roller bearings: Bearings with a NON-SPHERICAL moving part

Cylindrical roller bearings

Cylindrical roller bearings

In these bearings the rolling element is cylindrical instead of spherical. this will enhance the bearing load capacity and makes the bearing performance steadier. Roller bearings, on the other hand, are not ideal for heavy axial loads.

Accessories and maintenance products

Failure in bearing operation has the potential to cause irreversible harm to industries. As a result, not only the use of original items with the requisite quality and standards is essential, but there is also a necessity for standard instructions for installation, maintenance, lubrication, and replacement to be trained and used in a timely manner.
